Reaction Steps

To 7-[(3R)-3-[(1,1-dimethylethoxycarbonyl)amino]-4-(3,4-difluorophenyl)butanoyl]-2-(trifluoromethyl)-5,6,7,8-tetrahydroimidazo[1,2-α]pyrazine (110.8 mg, 0.226 mmol, from Step C) was added 2 mL of methanol saturated with hydrogen chloride. The reaction was stirred at ambient temperature for 1 h. Concentration gave 89.5 mg of the title compound as a foamy solid. 1H NMR (500 MHz, CD3OD) δ 2.97–3.10 (m, 4H), 3.91–4.34 (m, 5H), 4.90–5.04 (m, 2H), 7.16–7.33 (m, 2H), 8.01–8.08 (m, 1H). ESI-MS 389 (M+1).
